ATTINY167-15SZ

Overview

The ATtiny167-15SZ is an 8-bit AVR microcontroller featuring 16 Kbytes of in-system programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates at speeds up to 16 MHz within a voltage range of 4.5 V to 5.5 V. The device includes a certified LIN controller, 10-bit ADC with 11 single-ended channels, and multiple timers. It utilizes a 20-pin SOIC package and supports an extended automotive temperature range from -40°C to +125°C.

Feature Summary

• Integrated LIN 2.1 and 1.3 controller for automotive network communication
• High-performance 8-bit AVR RISC architecture with single-cycle execution
• Comprehensive analog peripherals including 10-bit ADC and on-chip temperature sensor
• Robust memory endurance supporting extensive write/erase cycles for Flash and EEPROM

Applications

• Automotive body electronics and control modules
• Local Interconnect Network (LIN) node implementations
• Industrial sensor interfaces requiring high precision analog conversion
• General embedded control systems operating in harsh environments

Procurement Notes

Verify the specific suffix 'SZ' corresponds to the 20-pin SOIC package and the -40°C to +125°C automotive temperature grade. Confirm that the speed grade '15' aligns with the required operational frequency and voltage constraints for your design. Ensure compatibility with existing toolchains for the AVR core architecture.

Selection Notes

Select this component when 16 Kbytes of program memory is necessary compared to the 8 Kbyte variant. It is suitable for applications demanding certified LIN bus connectivity alongside standard UART functionality. Consider the 20-pin SOIC form factor for PCB layout requirements and verify that the 16 MHz performance meets processing needs at the target supply voltage.

Part Context

This part belongs to the ATtiny87/ATtiny167 family, which shares hardware and software compatibility. The primary distinction between these devices is the Flash memory capacity. Both are designed for automotive environments, adhering to AEC-Q100 Grade 1 standards and ISO-TS-16949 manufacturing processes for high reliability.

Replacement Considerations

The ATtiny87-15SZ is a direct functional substitute if only 8 Kbytes of Flash memory is sufficient for the application. Both parts share identical pinouts, peripheral sets, and instruction sets.
